Over the course of the past 15 years, Jake Shimabukuro has challenged and changed all notions of what was possible with a ukulele. But on his latest album, “Trio,” the acclaimed musician begins a bold and exciting new chapter in his already remarkable career.

Unlike previous releases on which Shimabukuro sometimes utilized studio musicians recording songs he’d already written, “Trio” is radically different: it’s a true band album. The only sounds on the record are performed by himself, bassist Nolan Verner and guitarist Dave Preston, and many of the songs were composed spontaneously in the studio. In this way, “Trio” lives up to its title as a fully immersive document of the sonic alchemy the three musicians achieve on stage.

Music fans will no doubt hail Trio as a highwater mark for Shimabukuro, and the artist himself regards it as a personal best. “Beyond playing the ukulele, I’ve really tried to grow as a writer,” he says. “Spending time in Nashville and being around great songwriters has inspired and influenced me, and of course, working with Nolan and Dave has brought me to musical places I never thought possible. I’m so proud of the music we make together, and I can’t thank them, R.S. Field and Van Fletcher for everything that they do. This record really captures our collective spirit, and I can’t wait to get out there and play these songs live.”
